--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
In the .gimple dump there's no line 6 on stmt locations but .lower has a new
debug stmt with that line, likely from the goto location of the backedge.

I'm not sure this is "easy" to fix.  Oddly enough at -O0 we don't have
debug stmts and thus this line is not mentioned.
